A reaction that produces acid anhydride is a dehydration reactions. For example, acetic acid forms acetic anhydride and water by a dehydration reaction. The formula for this is: 2 CH3COOH → (CH3CO)2O + H2O Many polymers are produced by the dehydration reaction including alcohols converting to ...

Under what abiotic conditions can monomers spontaneously form polymers? a. When water evaporates from a hot surface. b. When ribozymes are present to catalyze the reaction. c. With the addition of water. d. By biogenesis. What kind of ...
Thermosets are a class of polymers that start out as small molecules (monomers and oligomers) and during a chemical reaction polymerize into a network structure. In the final fully cured state, the crosslinks join the chains together providing both good mechanical properties, but thermosets will not...
Polymers are formed when several single units of molecules (referred to as monomers) are joined together by a chemical bond. In the case of glucose, a simple sugar monomer, or what we can specifically call a monosaccharide (mono-single, saccharide - sugar), it combines with other glucose mol...
Polyester is a manufactured product, usually a textile, that is made from synthesized polymers. It tends to be very resilient, quick drying, resistant to biological damage such as mold and mildew, easy to wash and able to hold forms well. Although polyester is often maligned as a textile, ...
Additionally, polystyrene is considered a thermoplastic polymer, a classification that is determined by the material's reaction to heat. Thermoplastic polymers can be easily melted and reformed, making them easy to recycle. In contrast, thermoset polymers can only undergo the forming process once, mak...
Bark still forms when you use sugar-free rubs, so you know something else is going on. As the meat is cooking, the surface begins to dry out. Proteins on the meat’s surface bond together and form polymers. This is called the Maillard reaction. The result is a hard layer on the surf...
Polymers are tailored through the polymerization process, where the choice of monomers and the conditions of the reaction can alter the material's properties. 9 What advantage do laminates have over natural materials? Laminates can offer improved durability, resistance to wear and moisture, and consis...
Determines its ability to form polymers. Ethylene is a monomer with a double bond, allowing it to polymerize into polyethylene. 11 Dimer Homodimers and heterodimers, based on the monomer units. Collagen is a protein that forms heterodimers. 7 Monomer Can form various types of polymers through di...
